After seeing small declines for four of the last five weeks following the previous record high, the national average retail price of a gallon of diesel soared upward 8.2 cents to set a new record for the week ending Monday, July 7. The $4.727 price is 0.4 cent higher than the previous record high and $1.878 higher than the same week last year, according to the U.S. Department of Energy.
The average U.S. price now has been above $4 for 13 weeks, setting the previous all-time high of $4.723 on May 26.
